The Sname= Keyword

The sname= keyword must be present to define the short or abbreviated
name of the classification. The name is taken to begin with the
first non-blank character following the blank after the keyword, and continues up
to the next semicolon or the end of the line. The name
can contain blanks. A particular sname value should not be specified more than
once in the encodings file. If sname= is specified more than once
for the same classification, all specifications except the last are ignored. Hence,
sname= should be specified only once.

The short name specified is used when producing human-readable classifications in sensitivity
labels and clearances. The short name specified can also be entered by
users any time a classification is needed (in sensitivity labels, information labels,
and clearances).
